Today in 1975, US Patent 3897569 A was issued, an invention of Ronald Horgan, for his “Malting.” Here’s the Abstract:

An improved malting process comprises the steps of steeping barley or other cereal grain to initiate germination thereof, subjecting the germinated grain to a treatment to restrict further growth and respiration of the grain, and malting the grain in a relatively short period. The treatment may be a mechanical treatment such as pumping the grain in water, or it may be a temperature or chemical treatment. The subsequent malting may be carried out at a temperature between 20 DEG and 40 DEG C and the malting period is less than 48 hours.
